Subject: Fix consumer lttng_consumer_poll_socket poll revents check bug
X-Git-Tag: v2.0.1~8
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=3654a23ff4d32ecb2b70142dcfd0328df2fe73fb;p=lttng-tools.git

Fix consumer lttng_consumer_poll_socket poll revents check bug

Was causing the sessiond to fail to receive streams under heavy load,
because this test needs to be done with a mask rather than equality.
Testing equality was failing as soon as POLLPRI (or any other flag) was
set.
